Swax Lax goalie training balls feature numbered panels, which allow coaches to train goalies to develop a laser focus by having them call out the numbers and colors of incoming shots. Well-known goalie coach Ted Glynn has tested the product for us and says, "We love the new Swax Lax goalie training balls, they are awesome for targeting and for hand-eye training for young to advance keepers." This set contains three training balls per pack.
